STEERlNG-PROPELLER.

SPECIFICATION forming part of Letters Patent No. 51 1,806, dated January 2, 1 894.

Application filed February 27, 1393. Serial No. 463.807. (N model.)

To all whom it may concern: when the latter is in position, and the sec- Be it known that I, SAMUEL SEABURY, of tions of. the globular bearing adjusted with Bayonne, in the county of Hudson and State their faces in proximity to each other, the of New Jersey, have invented a new and usesaid sections are locked against longitudinal 55 5 ful Improvement in Steering-Propellers, of displacement along the shaft by a nut a which the following is a specification. screwed onto the threaded end a of the shaft. Myinvention relates to an improvement in The sections O and C may be keyed to the steering-propellers and more particularly to shaft to rotate therewith by a feather a and the means for securing the propeller to the groove a to drive shaft.

The journal shaft, a journal piece comprising a single piece D is made to straddle the shaft Aand forging having twosets of journals located the opening 61 therein through which the 20 upon axes atnight angles to each other, one shaft extends is elongated and preferably has set of journals being mounted in bearings in its ends beveled, as shown at (1 to permit the the aforesaid globular bearing and the other rocking movement of the piece D on its jourset having the propeller hub mounted therenals cl. Provision is further made for such on, the propeller hub at the same time emrocking movement of the journal piece by 25 bracing and bearing upon the curved face of openings 0 and c in the globular bearing, the globular bearing. which openings extend in opposite directions In the accompanying drawings, Figure 1 from the center of the globular bearing to its represents in side elevation, a four bladed outer surface, and are formed with a view of steering-propeller in operative position at the the free passage of the opposite ends of the o stern of a boat. Fig. 2 is an enlarged horipiece D back and forth in its rocking movezontal section through the globular bearing, ment. The piece D, because of the means for showing the propeller hub turned off to one adjusting it in working position, may be side, the blades of the propeller being omitforged of a single piece of material. ted, and Fig. 3 is a transverse section through The hub of the propeller is formed in quar- 5 the globular bearing, showing the hub of the ter sections E, provided with connecting propeller in position in alignment with the flanges e, and adapted, when assembled, to drive shaft. embrace the globular bearing, but cut away The drive shaft is denoted by A. Its end, at the end toward the stern post to permit which protrudes through the stern post B on the hub to assume varying positions on the 0 0 the vessel, has keyed thereon a globular bearbearing. The said quarter sections E are furing connecting the two sections 0 and O. ther provided on opposite sides of the hub The meeting faces of the sections 0 and O with bearings e for the reception of the set interlock, a recess 0, which extends diametof journals d on the journal piece D.

Half bearings c and c are end of the hub, has a hearing it in an arched formed in the bottom of the recesscand face rudder post H pivoted to the boat above and of the tongue 0' respectively, upon opposite below the propeller, as for example as at h 50 sides of the shaft A, for the reception of the and h and in the plane of the center of the set of journals (Z of the journal piece 1) and globular bearing.

The fit of the hollow propeller-hub to the globular bearing is preferably such that, while the hub may rock on the journals (1 of the journal piece, and is locked to rotate with the drive shaft and globular bearing by such journal connection, the interior of the hub will nevertheless bear upon the curved face 'of the globular bearing rather than on the journals cl.

To insure the openings 0 and c from the accumulation therein of any foreign substance, I provide openings 8 in the quarter sections E through which a current of water will naturally rush when the wheel is in motion.

By the above structure and arrangement of parts, I am enabled to locate the combined main driving-and-steering wheel under cover of the stern in proximity to the stern post and supported upon an extended bearing directly upon the main shaft and to provide a strong economical journal piece in a single forging, while the manipulation of the wheel is easy and its frictional wear upon its bearing slight.

While I have chosen a propeller wheel to illustrate a practical embodiment of my invention, it is obvious that the connection may be utilized to connect the hub of a pulley or power transmitting shaft to the drive shaft, and such applications of the above described connection are intended to be embraced in this invention.

What I claim is 1. The combination with a shaft having a globular bearing fixed thereon, of a part to be driven having a hollow hub for embracing the globular bearing and having a bearing contacttherewith, and a connecting piece having a rocking engagement with the globular bearing, the hollow hub having a rocking engagement with the connecting piece, substantially as set forth.

2. The combination with a shaft having a globular bearing fixed thereon, of a part to be driven having a hollow hub for embracing the globular bearing and a journal piece formed of a single forging and provided with two sets of journals, one for connecting the piece with the globular bearing and the other set for connecting the hollow hub with the journal piece, substantially as set forth.

3. The combination with a shaft having a sectional globular bearing fixed thereon, and a journal piece mounted in the globular bearing, of a part to be driven having a hollow hub for embracing the globular bearing, the said hollow hub having a rocking connection with the journal piece, substantially as set forth.

4. The combination with the drive shaft having a globular bearing fixed thereon, of the propeller wheel provided with a hollow hub adapted to embrace and bear upon the globular bearing, a rocking connection between the hub and the globular bearing and the swinging rudder post connected with the hub of the propeller wheel, substantially as set forth.

5. The combination with the drive shaft- SAMUEL SEABUR/Y.
